PIHCK.

SPECIFICATION forming` part of Letters Patent No. 293,809, dated February 19, 1884. Application filed June 9, 1883. (No model.)

To ((,ZZ wwm it 772,114/ 8072087112,.-

Be it known that I, GEORGE W. Smronns, of Boston, in the county of Sut'folh and State of Massachusetts, have invented certain Improvements in Bricls, of which the following is a specification.

This invention has for its object to provide a bricl: of such form that when a number of the bricks are laid to compose a wall spaces will be formed immdiately behind the seams or joints between the Vertical surfaces of the brioks at one side of the wall for the reception of mortar forming a part of a Vertical coating laid against the side of the wall, and holding said eoating in place against the wall, the bricks serving as substitutes for laths.

To this end my invention consists in the irnproved form of bricl; which I will now pro eeed to describe.

Of the aecompanying drawings,forn 1ing a part of this specification, Figure l represents a side view of a bricl: embodying my invention. Fig. 2 represents an end view of the same. Fig. 3 represents a Vertical section, showing` a wall built of niy improved brioks. Fig. 4 represents a perspective view of another form of bricl: embodying my invention. Eigs. 5, 6, and 7 represent modifieations.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention, I provide a brick, a, with grooves Z), preferably of a V shape. Said grooves, as shown in .Figs 1 and 2, extend entirely around the bricks, in close proximity to and parallel with the face which forms a part of the Vertical surface to which the coating of mortar is to be applied. `When the bricks thus formed are laid in courses to form a wall, as shown in Fig. 3, the grooves in the proximate surfaces of the bricks form dovetail pockets or spaces, the narrower ends of which are close to the surfaces of the briolrs. It will be seen that a coating, c, of mortar laid against the Vertical surface of the wall will fill the dovetail pockets above described and form ribs of mortar, said poclets thus firmly securing the eoating c to the wall. The grooves Z) may extend around the brlck parallel with one of the ends thereof, as shown in 4-. It is not absolutely necessary to make the grooves Z) in both of the opposite surfaces of each brick. If desired, the upper side may have a groove and the under side none, as shown ilrFig. 5, r vice versa.

The grooves Z) mayv be rounded, as shown in Fig. 6, instead of Vshaped. Fig. 'T shows a V-shaped groove having both of its sides in clined.

The bricks having the grooves formed as shown can be molded at one operation as readily as plain bricks.

An inside wall eonstructed of my improved brieks a, should be separated from the outer or main wall of the building by an air-space, for the purpose of leeping the brieks and their coating o in a dry condition. The two walls should ht? tied together in any suitable manner.

It is obvious that the improved bricks can be used for an outcr wall, the grooves reeeiving and holding stueco coating applied to the surfaces of the wall.

It will be seen that a wall constructed described would be practically fire-proof.

I elaim- A brick having a marginal groove formed in one or more of its sides in close proximity to one of its Vertical faees or ends, said grooves being formed to constitute a space between the proximate surfaees of two bricls of suitable form to receive and secure mortar, as set forth.

In testilnonywhereof I have signed my name" to this specification, inthepresence of two sub scribing witnesses, this 2d day of June, 1883.
